hello, I have one code:
import cv2
cv2.VideoCapture(xxx.mp4/avi)
print vidcap.isOpened()
it still is False. I google for much time and rebuild ffmpeg and opencv. It they do not work.
anyone can give some advises? I use ubuntu16.04 anaconda2
thank you very much~~
besides, I have python-opencv3.2 for python, but I install opencv2.4.13 from source. So must I install opencv3.2 from source?
Your url cv2.VideoCapture(xxx.mp4/avi) isn't correct.. .mp4 is already a video type and doing \ means you want to go inside the directory even though xxx.mp4 is not a directory but a file.
I think OP means he tried both ways .avi and .mp4 and none worked.
First thing is to make sure the name and path of the video file is correct.
If there is nothing wrong with the path, than this is almost always a codec problem. OpenCV is trying to find the codec to open the video and is not finding it.
Download a codec package into your system (easy to find on google) and then try to run the same code again. I've seen a lot of people solving this problem just doing this.

check cv2.getBuildInformation() to see, if there's support for video files at all.
